What tectonic plates were involved in the Indonesian earthquake 2018?
The January 15 event was a shallow crustal earthquake at the boundary between the Sunda plate and the Banda Sea microplate at a focal depth of 18 km. The earthquake occurred along the Mamuju–Majene thrust fault, which is known to be an active seismic source that has caused several deadly earthquakes in the recent past.
What type of plate boundary is Sumatra Indonesia?
Sumatran Subduction Trench
This plate boundary is called the Sumatran Subduction Trench, and it is where the oceanic Indian/Australian plate is slowly descending beneath (subducting under) the continental Eurasian plate at a rate of about 4.5 cm/year (2 inches/year).
What are the 3 major tectonic plates?
There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.
Where is Indonesia located?
Southeast Asia
Indonesia, country located off the coast of mainland Southeast Asia in the Indian and Pacific oceans. It is an archipelago that lies across the Equator and spans a distance equivalent to one-eighth of Earth’s circumference.
Why does Indonesia have lots of earthquakes?
Indonesia is prone to earthquakes because it lies on the so-called Ring of Fire – a line of frequent quakes and volcanic eruptions on the Pacific rim. The Indian Ocean tsunami of 2004 killed 170,000 people on the Indonesian island of Sumatra after a quake of magnitude 9.1.
Is Indonesia on a convergent plate boundary?
